/**
 * Combine the nebula-ospackage-application with the nebula-ospackage-daemon plugin. As with the nebula-ospackage-application,
 * this is opinionated to where the application lives, but is relatively flexible to how the daemon runs.
 *
 * TODO Make a base plugin, so that this plugin can require os-package
 *
 * Usage (from nebula-ospackage-application):
 * 
 *     User has to provide a mainClassName
 *     
User has to create SystemPackaging tasks, the easiest way is to apply plugin: 'os-package'
